Question

我有一个php Mysql交互，我希望通过ONCLICK事件触发Mysql搜索。

iv考虑使用JS函数或JQ并解析通过JS函数选择的ID，但后来我不确定如何重新执行php以使用新的JS Veriable重新搜索数据库......

下面的代码是准确的，是我正在使用的...

我将如何使用新ID执行php ..非常感谢...

Then re-execute the folling php

＆＃34;没有张贴＆＃34;意思是＆＃34;没有GET＆＃34;还有？否则，您可以将检索脚本放在不同的文件中，并使用jQuery.get或XMLHttpRequest进行调用。

从Onclick执行Php Mysql函数没有POST
